Cristal PoolTest for chlorine + pH

Cristal Pooltest Chlorine + pH, 50 test strips

A pool needs regular maintenance and even if you use much less chemicals and less cleaning effort with PureFlow filter material, you still can't do without them. We offer you the following for testing chlorine and pH:

2 in 1 test strips for swimming pool water analysis.

For measuring free chlorine and pH in the pool or whirlpool.

These two water values ​​should be checked at least once a week!

Scope of delivery: 50 pieces in the can.

Test strips with two measuring fields for easy, direct measurement of pH and chlorine content in pool water.

Application:

1. Dip the test strip into water for 1 second and then remove it again. Do not shake off water drops on the test strip.

2. Hold the test strip horizontally in your hand with the test pads facing upwards for 15 seconds.

3. Determine pH value and free chlorine value by color comparison.

The ideal pH value should be 7.0 - 7.4 and the chlorine value at least 0.5 mg/L.

Contents - One can contains 50 strips.

Accuracy of pH measurement:

Small differences in the pH reading between the water test device (with phenol red tablets) and the PoolTest test strips can never be completely avoided.

In general, the method using phenol red tablets is the more precise method!
However, the simpler and faster measurement with the test sticks often outweighs the lower accuracy.

The pH value in the swimming pool water does not always have to be accurate to the decimal place!
In practice, it is sufficient if the pH value is within a certain range.
The ideal range is between 7.0 and 7.4. This accuracy can be achieved with both test methods.
However, if the display differences are larger, it should be checked why the display differences occur.

The way the test sticks are stored also affects the accuracy of the measurement. If the container was not properly sealed, moisture can enter and the test sticks quickly become inaccurate.
